SPRING SUSPENSION.

Patented July 2, 1912.

Application led October 24, 1910. Serial No. 588,806.

To all whom t may concern Be it known that I, FRANK B. STRATFORD, acitizen of the United States, residing at Jersey Cilgy, in the county ofHudson and State of ew Jersey, have invented certain new and usefulIImprovements in Spring Suspensions, of which the following is aspecification, reference being had therein to t ie accompanying drawing.

My invention relates to improvements in spring suspensions and hasparticular reference to the same as ap lied to vehicles, moreparticularly automobi es.

Referring to the accompanying drawings, Figure 1 illustrates in brokensection and in dotted outline, the front partof an automobile showing anap lication of one form of my invention, and `ig. 2 illustrates amodification.

6 is the body of the vehicle mounted upon the main framework 7 in theusual manner, and 8 is a usual form of spring found in vehicles of thischaracter. One end of the spring is preferably secured to the framework7 by a suitable bearing such as 9 and the other end is preferablymounted in a suitable bearing such as 10 which also serves as a bearinvfor the sprin 11. The spring 8 preferably rests upon t e axle 12 asshown. Upon the upper part of the framework 7 is provided a suitablebearing such as 13 in which the spring 11 may be pivotally mounted, theother end of the spring 11 being secured to a suitable spring such 'as14, also mounted upon the framework 7. This arrangement is found toincrease the resiliency of bearing without weakening the constructionand vehicles provided with springs arranged in this manner are found toride with a minimum of jar or shock, being far more comfortable thanwheipprovided with the usual arrangement of springs.

In Fig. 2, the spring 11 is shown provided with a spring above and belowthe inward end 15 as shown at 14 and .14 by mounting the same' in asuitable bracket such as 16 and the inward end of the spring ispreferably made solid.

Of course it will be understood that various other modifications may bemade without departing from the spirit of the invention as set forth inthe claims.

Hav'ingvdescribed my invention, what I claim as new, and desire tosecure by Letters Patent is:

1. A spring suspension for vehicles comprising,.1n combination, asupporting spring connected at one end to the body of the vehicle and atan intermediate point connected to the running gear, a second springsecured at an intern'iediate point above said body and at one endconnected with the opposite end of said supporting spring, anotherspring secured above said body and connect4 ed w1th the opposite end ofsaid second spring, whereby the upward movement of said opposite end ofsaid second spring causes said other spring to become extended.

2. A spring suspension for vehicles comprising, 1n combination, a suportin spring connected at one end to the ody o the vehicle and at anintermediate point connected to the running gear, a second springsecured at an intermediate point above said body and at one endconnected with the opposite end of said supporting spring, said secondspring having a solid extension, another spring secured above said bodyand said solid extension of said second spring secured to said otherspring, whereby any movement of said solid extension is opposed by saidother spring.

In testimony whereof I atlix my signature in presence of two witnesses.

FRANK B. STRATFORD.
